The warship was able to finish its five-and-a-half-month deploymentm and Capt. Chris Cegielski, in charge of the warship during the collision, kept his job until last month, when he handed command to Capt. Jen Ellinger.

However, "administrative and disciplinary actions" were taken against Cegielski, his executive officer and several members of the Lake Champlain's watch team after the crash, U.S. Pacific Fleet spokeswoman Lt. Cmdr. Nicole Schwegman said in an email.

Results of an accident investigation, which concluded in June, won't be released to the public pending litigation, she said.

The mishap was part of a slew of accidents involving U.S. warships in the Pacific this year.

In January, the USS Antietam ran aground and spilled roughly 1,100 gallons of hydraulic fluid into Tokyo Bay; in June, a collision between the USS Fitzgerald and a merchant ship killed seven sailors; and last month, a collision between the USS John S. McCain and an oil tanker killed 10 sailors.

In response to the collisions, the Navy announced the creation of the Naval Surface Group Western Pacific to help assess whether ships in the Pacific are ready to deploy. The unit is led by Capt. Richard Dromerhauser, a former Fitzgerald commander who previously served as the head of 6th Fleet's Destroyer Squadron 60, based out of Rota, Spain.
